+# Obsidian
+
+## Overview
+
+Local-first note-taking and knowledge management app, run as a web-accessible desktop via KasmVNC.
+
+## Project Details
+
+-   **Project Repository:** [obsidian.md](https://obsidian.md/)
+-   **Container Image:** [linuxserver/obsidian](https://docs.linuxserver.io/images/docker-obsidian/)
+-   **Documentation:** [help.obsidian.md](https://help.obsidian.md/)
+-   **Reverse Proxy Port:** `3000`
+
+## Getting Started
+
+1. Start the container: `docker compose up -d`
+2. Open http://localhost:3000 in your browser
+3. Follow the initial setup wizard to configure the application
+
+## Environment Variable Notes
+
+    OBSIDIAN_PUID / OBSIDIAN_PGID – ownership of the vault files
+
+## Volume Notes
+
+    /config – Obsidian settings and your vaults
+
+## Network Notes
+
+Requires proxy network
+
+## Docker Run
+
+```bash
+docker run -d \
+  --name obsidian \
+  -p 3000:3000 \
+  -e TZ=America/Vancouver -e PUID=1000 -e PGID=1000 \
+  -v /data/obsidian/config:/config \
+  lscr.io/linuxserver/obsidian:latest
+```
+
+## Additional Notes / Gotchas
+
+This streams the Obsidian desktop app to your browser (KasmVNC) — it is unauthenticated by default, so keep it behind the proxy with auth. Obsidian itself is proprietary (free for personal use).
